To use these women's t-shirts and premium t-shirts, simply put them on and enjoy the comfort! When it's time to clean them, machine wash them cold inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. For the best look, hang them to dry after washing. You can also tumble dry on cool or low heat. But remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry cleaning the shirts to keep them in good condition.
